Sweet...I have a non-gas wire fed MIG.So took my Vulcan to this shop,greasy lil corner shop been workin on bikes for 30 years (??)...told dude to check charge system...then showed him how nice/easy bike starts with full charged battery.He even commented "Sounds good".Week later he gives me a price on Stator RnR,I tell him nah,coming to get the bike...I go to pick up my bike...SUCKER AINT GONNA START/RUN...he cut the wires to my rectifier!!He showed me "melted plug" at rectifier...OK but still my bike was startin/runnin when brought to his shop!!

vulkan 'Course the 'ol VN 750 in the shop now...when the battery "dies"...the bike "DIES" too!!So was getting by with trickle charger...you know ride good few miles,12-15 then start'er up head home to the trickle charger.But I figure its only a matter of time and that style riding probably not good for the bike/system either.(Also who the HELL wants to ride here/there a little...hope to make it home??)

15v

The stator legs were about 12 -15v AC . No short to ground, and all legs about the same. I am really considering the external alternator. Then, no more charging problems, and even if I am on a trip and the alternator goes out, I can pull into any auto parts store and change it in the parking lot, lol. I don't mind doing the stator job, but not knowing how long a new one will even last bothers me.

And as for the input on the two-wire and blue-wire mods:

I had no probs with cold starting before the 2-wire mod, but it does seem to start quicker, like almost instantly and I never have to choke, and never did.

I had probs before once in awhile with taking a few tries to start when hot, that seems to have been fixed by the 2-wire mod.

The blue wire mod worked fine for me, did not drain enough juice on start to notice slower cranking at all. I now run with no headlight or tail light fuse (Brake lights and signals still work) because I am riding with no stator and don't ride at night.


When and if I do the external Alternator mod, I will be getting rid of the JB with the help of the posts from this forum, and I have a service manual with all the wiring diagrams.

Spockster Yes, new stators come with a new grommet. What kind of shop does that sort of work?!!

What number did you get for AC volts? What do you get for DC volts at the battery now?

Thanks for the feedback on the Two-Wire Mod.

New R/R

Hey Doc,

I put on a new stock R/R, the plug was fried, I put new terminal ends on the wires. I also removed the bullet connectors on the stator wires and soldered them. I checked every other electrical connection on the bike for corrosion or burnt signs. I did the two wire mod and the blue wire mod which helped my starting big time. I took the JB off and it looks fine, cleaned the two plugs on the JB real good with contact cleaner and the plugs look fine. I have AC output on all three stator wires but it is half what it should be and for some reason does not go up with throttle increase. The PO said he just paid a bike shop to fix it and has no idea what stator they put in it. I have a feeling that they put in a used stator, since there was no grommet on the stator wires where they leave the sidecase. Don't new stators have the grommet on the wires when you buy one?

If I don't do the external alternator mod, my second choice is putting a second, smaller AGM where the goats belly used to be, switched so I can just switch over to it to get me home if my main battery dies.

One of the reasons I hesitate to just replace stator is that I finally got ahold of the PO and he said he just paid 500 bucks to have the stator changed, showed me the receipt, and it lasted 2 months.
how's your rectifier and it's connections?
